## API2D

API2D is a payment-and-routing layer that sits in front of the world's major language and image models. Instead of managing billing with each provider separately, you register an API2D account, top it up, copy the issued key and paste it into any client that supports a custom API base URL. Because the interface mirrors OpenAI's own specification, most existing tools, SDKs and self-hosted chat UIs work without code changes.

The platform bills in points (P) rather than a fixed monthly subscription, so cost tracks actual token consumption. According to API2D's own documentation, overall pricing is kept at roughly 1.5x the underlying provider's official rate, with a minimum per-request charge and free cached responses. Streamed GPT-4 replies are billed differently because they hold a connection open, and media-heavy endpoints add a modest bandwidth fee.

Beyond pure relay, API2D layers on value that a raw endpoint does not offer: response caching, retrieval-augmented search, drawing tools and an agent/reseller program that lets larger accounts create and price their own sub-keys. It is aimed at Chinese-speaking developers and enthusiasts who want frictionless, domestically payable access to frontier models. For anyone evaluating it, remember that API2D is an independent third party and not affiliated with OpenAI, Anthropic or the other model vendors.

**Pricing & Plans:** Pay-as-you-go in points (P); overall cost roughly 1.5x official provider pricing, with free cache hits and a minimum per-call charge. Recharge via WeChat, Alipay, Chinese bank cards or Stripe. Points expire 180 days after your last top-up.

- **OpenAI-compatible endpoint:** One base URL and key work with virtually any app, SDK or self-hosted chat client that supports a custom API address.
- **Multi-provider model access:** Route requests to OpenAI models, Claude, Stability diffusion, Azure TTS and vector database services from a single account.
- **Points-based billing:** Consumption is metered in points with a published multiplier, so you pay for what you use rather than a flat subscription.
- **Free response caching:** Identical request bodies return cached answers for free for 24 hours, and a header can disable caching when freshness matters.
- **Reseller and grouping tools:** Larger accounts can batch-create keys, set default models and resell access through their own pricing pages.

**Strengths:** Works with the large ecosystem of OpenAI-compatible tools out of the box; Point-based billing means low commitment and granular cost control; Response caching can make repeated queries effectively free; Built-in enhancements (search, knowledge base, drawing) go beyond a plain relay

**Limitations:** Cost runs above direct provider pricing once the multiplier applies; Points expire 180 days after the last top-up, so balances need periodic renewal; No monthly plan — heavy users must estimate spend from token usage; Pricing calculation is complex because of minimum charges and bandwidth fees

## OminiGate

OminiGate is an AI API gateway built for teams that are tired of managing separate keys, SDKs, and billing accounts for every model provider. It exposes one OpenAI-compatible endpoint and charges a single prepaid balance across text, image, and video generation. The model catalogue spans major vendors — OpenAI, Anthropic, Google, xAI, Mistral, DeepSeek, Qwen, Moonshot, MiniMax, and others — alongside image and video systems such as Flux, GPT Image, Seedream, Veo, Seedance, and Kling. Because routing is handled server-side, switching models is generally a one-line change in application code.

Under the hood, OminiGate keeps connections to multiple upstream providers for each model and routes requests intelligently, failing over automatically when one provider degrades. It also exposes real-time price comparison so you can route work to the cheapest viable option. Billing is purely usage-based: tokens for text, per image for image generation, and resolution and duration for video, with no subscription tier required. The first API key is generated automatically at signup so a developer can send a test call within minutes.

The platform is also built with a security posture aimed at production teams. It enforces a zero data retention policy, so prompts and completions are not stored, and encrypts traffic end to end with TLS 1.3. Enterprise plans add volume discounts, dedicated account management, custom uptime SLAs, SSO/SAML, priority support with under an hour response time, and configurable data residency. Cards are processed through Stripe, and balance is credited immediately.

**Pricing & Plans:** Usage-based with no subscription: pay per token for text models, per image for image generation, and by resolution and duration for video. Credit is prepaid via Stripe and pricing is shown in real time on the pricing page; enterprise plans with volume discounts and custom SLAs are available on request.

- **Video generation API access:** Access mainstream text, image, and video models from many providers through one endpoint and one API key, with a single balance covering all of it.
- **OpenAI and Anthropic compatibility:** Built on the OpenAI API specification and also compatible with Anthropic-style calls, so existing SDK code works after a two-line change.
- **Intelligent routing and failover:** Multi-provider automatic failover, smart load balancing, and redundant routes per model, backed by a 99.9% uptime guarantee.
- **Transparent usage-based pricing:** Pay per token, per image, or per video second with no subscription, and compare real-time prices across providers to route to the cheapest option.
- **Security and data handling:** Zero data retention, TLS 1.3 end-to-end encryption, strict access control, and configurable data residency for enterprise plans.

**Strengths:** One key and one balance across text, image, and video models; Drop-in compatible with the OpenAI SDK, and Anthropic-style calls too; Automatic multi-provider failover instead of a single upstream dependency; Zero data retention with TLS 1.3 encryption

**Limitations:** Actual spend depends on upstream model prices, so cost forecasting takes discipline; Requests are proxied through OminiGate infrastructure, which some compliance teams must approve first; Prepaid-balance model means you manage credit rather than a flat subscription; Quality and availability of individual third-party models can shift independently of the gateway
